This scene had a bit of an odd start; I was reading a book about failed architecture projects, and came across images for a failed Crimean nuclear power facility back in the 1980s, that was abandoned in favor of Chernobyl by the Soviets. Their was a shot of a well, I am not even sure what it was for...but it got me thinking and then modeling. 
I liked the way it was coming along, then I used Kaiber to animate.
